Re: LA-1K use with lightning suppressor
|
Hi Brett, ? I mounted a Paradan Radio Dual Antenna Disconnector on my RG213 coax, unfortunately AFTER a lightning strike.? It is controlled by 12VDC from my Astron PS.? When the 12VDC is off, the Paradan unit is INOP and both coax feeds are shunted to GND.? It can be mounted anywhere but requires a 12VDC feed to function... draws 120mA when ON... insertion?loss is 0.05.? This is not a gratuitous 'plug' for the named product, just another lightning mitigation idea. 73, Jerry KB1N

Thanks Eric,
My plan is to install the Alpha Delta switch for the coax on the antenna side of the AT , on the outside wall of the shack, in a waterproof cable box I installed for the polyphaser lightning suppressors, which were attached to a bus bar and directly to the ground pole 1 foot away. I'm sure quite similar to what you did. That way I can walk to the cable box 10 seconds away, flip the switch to Com, close the box and Good Night Irene!

I have used Alpha Delta inline lightning arrestor for years with my LA-1K with no issues. Can they go bad and have a problem, yes. But like you I live in the South and it gets rough around here. Besides you need just the static discharge function on any antenna that is a none loop configuration, Dipoles, verticals and such.
Also with any random wire antennas you can get some wild voltages at the feed point.
